How about change the option name from --verbose to --syms or something else?

verbose is usually used to denote some logs which may useful for developers. However, the feature in this patch is intended for users, not developers.

[yonghong-song]

In bcc tools, --verbose is mostly used to print out the eventual bpf prog source. In a few instances, the --verbose is used to print out additional information. I think it is good idea to use an option like -a or --address in this case. We can reserve --verbose for future use.
